[ after experimenting with the code ... ]  Oh, I had been thinking that
PQconndefaults gives the same result as PQconninfoParse with an
empty-string argument, but that's not the case.  Indeed, the former
fills in default values as current values, but the latter does not.

The proposed wording change seems reasonable, except that "have a
corresponding value" seems a bit vague.  Maybe better "have a non-null
val field".
